Application filed September-17. 1883. lNo model.) i

To @ZZ whom it r11/ay concern.:

i Beit known `that I, LoUIs ANDRnws, a citiL zen of the United States, residing at Arkansas City, in `the county of Desha and State of Arkansas, have invented new and useful Improvements in Division Plates for Oil- Presses, of which the following is a specificak tion.

\ fro This invention relates to certain improvements in divisin-plates used in presses for extracting oil` fromeotton-seed, and thesaid invention consists in details of construction of `said plates wherebya more perfect extraction ofthe oil is effected, the use of the costly hair `mats now employed to hold the meall is dispensed with, and the oil is lprevented. from being reabsorbed into the cake after once being expressed therefrom. i

Referring to the drawings forming part of this specification, and-in which similar letters of referenceindicate like parts in the several views, Figure l represents a plan view of one vof the plates for oil-presses constructed accord y A ing to my improvement, a portion of the thin .25

l y moved to show the corrugations in the main perforated corrugated copper plate being replate; Fig. 2, a longitudinal section of a portion of the plate; Fig. 3, a side elevation or edge viewof a portionof the plate, showing the holes or drains for the oil. Fig. 4 reprev sents an end view of a portion of the press stand, showing two plates in position therein, one being in section. Fig. represents an end view, showing the grooved plates placed upon each other; and Fig. 6, a sectional detail o f the the plate. are so formed-that is, with a projecting portion, C', of a width relatively to the space be- G C are the fpress-plates, having alongthe top edge at each side verticallyprojecting anges D D, which extend the whole length of The bottom portions of these plates abut against the vertical side flanges. D, a space, d, being left between the ends of the corrugations and the inner sides of the flanges, the object of which will hereinafter appeal'. At the bottom of the depressions c, across the face of theplates C, are formed shallow channels, which extend entirely across the width of the plates and through the sidevertical flanges, D, and open just above the gutter A, as shown at F in Figs. 3 and 4. Transversely 'through the vertical flanges D, near the top edge there of, is formed a series of small holes, G, and at intervals along the channel A are vertical op eningsH through'the plates. K are guide ears or lugs,whieh, partially embracing the standards or pillars L of the press, hold the pilates in their proper relations.

Bis a sheet of No. 16 copper plate, corrugated so as to fit close upen the face ofthe cor# rugated press-plate C, between the flanges D, andvhaving a series of perforations, b, therein, arranged in transverse lines across said plate, and in such position relatively to thedepressions c in the press-plate as to come over the channels F. Because of the bottoni extension, C', of the plates O, iitting between the flanges D in the top of the next lower plate, the liability to break is avoided, should nothing be placed'between any two plates or unusual pressure bring two plates together. The faces ofthe plates also being parallel, any amount of pressure may be applied without danger, and being parallel, an equal pressure is exerted on all parts of the cake or body of material in the press, a uniform size and shape` is, therefore, given to it, which is an important matter. The rear back end of each division-plate is constructedwith ,a cross-rib, I,

on its upper side,which` extends above the top Y surface of Vsaid plate, and the bottom of said plate has a corresponding cross-recess, I', at its rear edge, which, when the plates are in position to press the mat, receives thetop rib. I, and, while serving to prevent the escape of the oil at this point, serves as a stop or limit for the insertion of the material between the press-plates, thereby preventing the too far insertion of the material upon the plate. llhe object of the perforated copper sheet is to per mit the ready passage of the expressed oil from the meal, but at the same time prevent the entrance of the meal in the channels or drains F. The top and also the bottom sur-` IOO and formed into a cakcin a preliminary press,

is placed upon a proper-shaped piece ot sheetiron and thrust between the' press-plates, and

then the sheet-iron removed, the sideiianges, D, and end cross-rib, I, acting as guides and enabling the workman to properly place the meal-sack. Upon applying the pressure, the oil, as it is expressed from the meal, passes into the several drains and is conducted where desired. The oil from the bottom ofthe cake, passing through the perforations bin the copper plate, enters the transverse channels F and escapes into the side gutters. A. The oil from the top of the cake iinds an escape through the drains G, through the tlanges D, and also enters the gutters A, from whence it is conducted through drains or openingsHto the storage-tank. By reason of the corrugations not extending entirely across the pressplates to the side flanges, D, the meal is prevented from spreading, and because of the corrugated perforated sheet B, the clogging of the drains F is prevented and the quick escape of the oil is permitted; also, by reason of this perforated plate, the cake is separated from the oil, and therefore reabsorption of the oil by the cake is prevented when the pressure upon said cakes shall have been withdrawn. The cake is therefore delivered in a compact dry state, and of a uniform size and thickness throughout its mass.

Referring to the drains A F G, for the oil, at the top of the plate, it will be noticed that they are on different levels, and that the two upper ones open into the side gutters through the side flanges D D of the pressplate C. It will also be noticed that by constructing the press-plate as described it forms a complete device, requiring no special construction of oil-mat, but allowing of the use of a woolen sack only to inclose the substances or cake.

" I claiml. In a press for extracting oil from cottonseed meal or other substance, the herein-described division-plate G, constructed with the corrugations c c', top side ilanges, D D, and top side gutters, A, outside of said flanges, the crossdepressions c in the top of the plate opening into shallow-bottom drain-channels F, which, exten ding across the plate at the bottom of said depressions, open through said side iianges, D, into the side channels, A, and the said side flanges having drains G, opening above said corrugations c into said side gutters, whereby the oil is drainedfrom the said division-plate through its side flanges, D D, both from the top and from the bottom of the cake while under compression, substantially as shown and described. 2. In a press for extracting oil from cottonseed meal and other substances, the divisionplate C, constructed with top side tianges, D D, and bottom extension, G, the latter being adapted to fit within the former when the plates are brought together, substantially as shown, and for the purpose described.

3. In a press for extracting oil from cottonseed meal and other substances, the divisionplate C, constructed with top side anges, D D, and bottom extension, C', the latter being adapted to tit within the former when the plates are brought together, the top and bottom surfaces of said division -plate being formed with cross-corrugations, the drains F G and the side gutters, A, on the upper side of said plate being arranged at diii'erent levels,

all constructed substantially as shown and de-V scribed.

-L In a press for extracting oil from cottonseed meal and other substances; the divisionplate C, constructed with top cross-corrugations, c c', the top side flanges, D D, the drains F G,'and the side gutters, A, in combination with a copper sheet, B, formed with crosscorrugations corresponding with those in the division-plate, and having perforations b, arranged in line over the cross drain-channels F, whereby said copper plate forms a permanent corrugated seat for the mat, conforming to the corrugations of the division-plate, substantially as described, for the purpose specified.

5. The combination, in a press for extracting oil from cotton-seed meal andv other substances, of the division-plate C, constructed with top and bottom cross-corrugations, the top side flanges, D D, the top drains, A G F, and the bottom extension, C, the latter adapted to tit within the former when the plates are brought together, with a permanent perforated copper sheet, B, conforming to the corrugations inthe top and bottom of the division-plates, forming a mat-seat placed within and between the said side iiauges, whereby the plates will match with solid surfaces on a level when brought together, as shown and described.

6. The herein-described division-plate, constructed with top side flanges and a bottom extension, the latter adapted to tit between the former when the plates are brought together, the cross-corrugations in the top and bottom surfaces, the top drains, A G F, and the top end cross-rib, I, joining the said side flanges, D D, whereby to form a stop to limit the placing of the sack of meal upon said plates, as shown and described.

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses. A
